The effect of Sodium Silicate and Sulphuer "from Mishraq "in Strength of Concrete

الملخص

The present work deals with was carried out sake of improving some physical properties
of this material by means of adding sodium silicates, Sulpher "from Mishraq ", In
small different percentages , has improved the quality of concrete via the increase of it’s
Compressive and the mortar tensile strength
The study showed that the addition mixture of sodium silicates, Sulpher Causing an
increase in the Compressive and the mortar tensile strength . When Comparison was carried
out with reference concrete mix.
All the above work was carried out at different ambient temperatures of 8, 30 and 50
Cº respectively sake for the of showing the effect of different temperatures on the concrete
Compressive strength
All the results indicated that the concrete Compressive strength and the mortar tensile
strength reached miximum at 8 Cº.
The values of the concrete Compressive strength and the mortar tensile strength refer to
standard specimens (Cubes) at the age of 7 and 28 days .
